Plugging the Standard Controls Shift Linkage Hole
My son was not happy with the looks of the plastic plug that came with the kit after converting to forward controls on his 2012 Street Bob. I was installing my new chrome outer primary that my wife gave me for Christmas and he asked if he could have my OEM outer primary cover that did not have the hole for the standard controls in it.
After removing his outer primary cover and discovering the dilemna he was not sure how to proceed. He knew he absolutely did not like the plastic plug in the outer cover and also knew he would never to back to standard controls.
We decided to tap and plug the hole to create a permanent leak free solution.
The hole was already the correct diameter for a 3/8" NPT (3/8-18) tap. We removed the small gasket which is sandwiched between the inner primary and the outer primary with standard controls.
Tapping the boss.
Be certain to place a towel just under the boss to prevent any chips or aluminum shavings from finding their way into the chain or housing.
Tap removed. The inner primary housing is a very good quality casting and taps very nicely. Be sure to apply some pipe sealant prior to installing the plug.
Completed job. Plug recessed nicely into the boss.
All in all a pretty easy 5-minute job to ensure a leak free solution. After completing the job I decided to google it to see how others have addressed this issue and it appears that the majority of people just live with the plastic plug and others use a small convex freeze plug to seal off the bore.
I feel that tapping and using a pipe plug is a much cleaner and more permanent leak free solution so I thought I would share it just in case anyone else runs into this issue.

Ya, they are proud of those gaskets aren't they? Although the job itself is easy enough the gasket is quite expensive.

The previous owner converted mine to forward controls and installed to plastic plug. It doesn't really bother me at all. Definitely not enough to make me go through all the hassle and money required to replace the outer primary cover with a new one and remove the mid control shaft and all that.
